Lamoureux dropped her shoulder, feinted to the left, and gracefully manoeuvred the puck around Canadian goalkeeper Shannon Szabados, before flicking a shot over the line from close range.

The move even has a name. "It's called 'Oops, I did it again,'" Lamoureux said, according to the BBC.

Here is the move in all its glory:

"I've done that thousands of times around tyres just set out on open ice," a "thrilled" Lamoureux said.

However, it has taken years of practice to get it right.

"I've butchered it a thousand times, ran into tyres, tripped over tyres just working on my hands," she added. "I'm just glad it worked out this time."

The match was tied at 2-2 when the penalty shoot-out was called, meaning whichever team won via sudden death would win gold.

Both USA and Canada had scored five penalties each by the time it was Lamoureux's turn, and her goal came moments before an unsuccessful Canadian penalty. USA had done it.

"This victory is special and it's going to give us an even bigger platform to make a bigger difference," she said.

Lamoureux's twin sister Monique Lamoureux-Morando, who scored earlier in the game, said: "It's a move that our coach Peter Elander worked on with us over the last four years, not just on the goalie, but against defenders.

"We've screwed it up plenty of times, but she pulled the perfect time to pull it off."
